Hi Brandy,
The headlights on your car run on separate fuses and have a separate relay, in your fuse box. Great idea to check that out. After checking the fuses and relay and find them to be OK and the new bulbs you installed are also good, chances are you could have a wiring problem. If you need assistance, Askpatty.com has some great shops listed on the site.

Brandy;This can be several things. Most likely it is a bad dimmer switch, but, as you mentioned, it may be a fuse or the headlight relay. It does seem, however, that it is not the bulbs. Hope this helps, thanks Super Girls Auto.

Brandy,
It*s best to test fuses with a probe light first to rule out any other problems. If you do not have a probe light, you may be able to find the exact fuse location in your owners manual and remove the fuse to visually inspect it. Other possible problems that could cause both lights to be inop would be a wiring issue or an issue with the switch.
